Effect of different autologous platelet separation techniques on perioperative outcome in patients undergoing major cardiovascular surgery: a retrospective cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo compare two autologous platelet separation techniques with traditional autologous blood transfusion, focusing on their effects on coagulation function and postoperative recovery, in patients undergoing major cardiovascular surgery.
methodsThis retrospective study analyzed clinical data from 220 patients who underwent aortic replacement surgery or valve replacement surgery at Hunan Provincial People's Hospital between January 2019 and December 2022. The patients were divided into three group based on their intraoperative blood management protocols: Group A (n=48, red blood cells (RBCs) + platelet-rich plasma (PRP)), Group B (n=92, RBCs + platelets (PLT) + plasma), and Group C (n=80, autologous blood). Preoperative and postoperative findings were compared among the groups, including coagulation function, liver and kidney function, aortic cross-clamp time, cardiopulmonary bypass (CPB) time, blood product transfusion volume, length of intensive care unit (ICU) stay, duration of mechanical ventilation, and total drainage volume.
resultsGroups A and B showed decreased postoperative D-dimer level, reduced prothrombin time (PT) and activated partial thromboplastin time (APTT), and increased PLT (
conclusionAutologous platelet separation enhances recovery by improving coagulation and reducing transfusions, with RBCs plus PRP scheme (Group A) best preserving liver and kidney function.
